🏗️ Part 3 — MVC in Rails: Models, Views, Controllers Explained

Rails uses the MVC architecture:

• Model: Handles data and business logic (ActiveRecord)
• View: Template files (ERB or HAML) rendered to HTML
• Controller: The glue, handling requests and sending responses

Example controller:

 class PostsController < ApplicationController def index @posts = Post.all end end 

And the view:

 <% @posts.each do |post| %> <h2><%= post.title %></h2> <% end %>
